59351d9b40 ppc patch queue for 2016-Sep-7
This is my first pull request for the newly opened qemu-2.8 tree.  It
 contains a heap of things that were too late for 2.7 and have been
 queued for a while.  In particular:
     * A number of preliminary patches for the powernv machine type
         * A substantial cleanup of exception handling which will be
           necessary to support running a TCG with hypervisor
           facilities
     * A start on support for POWER9
         * Some TCG implementations for new POWER9 instructions
         * Some TCG and related cleanups in preparation for POWER9
     * Some assorted TCG optimizations
     * An implementation of the H_CHANGE_LOGICAL_LAN_MAC hypercall
       which allows the MAC address to be changed on the PAPR virtual
       NIC.
     * Add some extra test cases for several machines (this isn't
       strictly in the ppc code, but is most value to ppc)
 
 NOTE: This pull request supersedes ppc-for-2.8-20160906, which had
 some problems.  Changes:
   * Dropped BenH's lmw/stmw speedups, which break for
     qemu-system-ppc64 on BE hosts
   * A small fix to Thomas' serial output test to avoid a warning on
     the isapc machine type.
   * Some trivial checkpatch fixes
 
 Note that some of the patches in this series still have large numbers
 of checkpatch warnings.  This is because they're moving existing code
 that predates most of the checkpatch style conventions.

d2ab58ffc9 tests: Check serial output of firmware boot of some machines
Some of the machines that we have got a firmware image for write
some output to the serial console while booting up. We can use
this output to make sure that the machine is basically working,
so this adds a test that checks the output of these machines
for some well-known "magic" strings.

29531542bc tests: Resort check-qtest entries in Makefile.include
The rather random list of check-qtest-xxx entries caused some
confusion in the past, where to use "=" and where to use "+="
(see commits 0ccac16f59 and 1f5c1cfbae
for example).
Sorting the check-qtest-xxx entries by architecure instead and
using some empty lines inbetween should help to ease this
situation a little bit, so that it is hopefully now obvious
that new tests should be added with "+=" instead of "=".
While we are at it, this patch also comments out two of the
"gcov-files-..." lines since the corresponding m48t59-test is
disabled for sparc and sparc64, too.

32f5f50dad spapr: implement H_CHANGE_LOGICAL_LAN_MAC h_call
Since kernel v4.0, linux uses H_CHANGE_LOGICAL_LAN_MAC to change lively
the MAC address of an ibmveth interface.

As QEMU doesn't implement this h_call, we can't change anymore the
MAC address of an spapr-vlan interface.

dd2fa4f72d ppc: Fix macio ESCC legacy mapping
The current mapping, while correct for the base ports (which is all the
driver uses these days), is wrong for the extended registers.

I suspect the bugs come from incorrect tables in the CHRP IO Ref document,
I have verified the new values here match Apple's MacTech.pdf.

Note: Nothing that I know of actually uses these registers so it's not a
huge deal, but this patch has the added advantage of adding comments to
document what the registers are.

3433b732a4 ppc: Make alignment exceptions suck less
The current alignment exception generation tries to load the opcode
to put in DSISR from a context where a cpu_ldl_code() is really not
a good idea. It might fault and longjmp out and that's not something
we want happening here.

Instead, pass the releavant opcode bits via the error_code.

There are a couple of cases of alignment interrupts that won't set
anything, the ones coming from access to direct store segments, but
that doesn't happen in practice, nobody used direct store segments
and they are gone from newer chips.

72073dcce0 ppc: Don't update NIP on conditional trap instructions
This is no longer necessary as the helpers will properly retrieve
the return address when needed.

57a2988b6f ppc: Don't update NIP in facility unavailable interrupts
This is no longer necessary as the helpers will properly retrieve
the return address when needed. Also remove gen_update_current_nip()
which didn't seem to make much sense to me.

0f72b7c682 ppc: Fix source NIP on SLB related interrupts
We need to pass it to the raise helper since we don't update it
before the calls.

Instead, pass GETPC() result to the corresponding helpers.

e41029b378 ppc: Don't update NIP in lswi/lswx/stswi/stswx
Instead, pass GETPC() result to the corresponding helpers. This
requires a bit of fiddling to get the PC (hopefully) right in
the case where we generate a program check, though the hacks there
are temporary, a subsequent patch will clean this all up by always
having the nip already set to the right instruction when taking
the fault.
